Worms squirming on a fishhook feel no pain -- nor do lobsters and crabs cooked in boiling water, a scientific study funded by the Norwegian government has found. "The common earthworm has a very simple nervous system -- it can be cut in two and continue with its business," Professor Wenche Farstad, who chaired the panel that drew up the report, said. Norway might have considered banning the use of live worms as fish bait if the study had found they felt pain, but Farstad said "It seems to be only reflex curling when put on the hook ... They might sense something, but it is not painful and does not compromise their well-being."
